SPRING STANCI-IION-'LOGK.

Specification of Letters Patent.

Application filed September 16, 1912.

Patented Aug. 26, 1913; Serial No. 720,636.

To all whom t may concern.'

Be it known that l, Mino B. HINER, a citizen oit the United States, residing at Alexandria, in the county of Hanson, State of South Dakota, have invented certain new and useful Improvements in Spring Stanchion-Locks; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rihis invention relates to stanchions and more particularly to spring locks thereof.

The object of the invention is to provide a spring lock mechanism, whereby a stanchion may be readily and securely locked in closed position.

Another object is to provide a spring lock ol" this character formed of two pieces of metal and resilient-ly held in normal position by means of a coil spring to lock the stanchion in closed position.

A further object is to generally improve and simplity the construction and operation et' devices of this character and at the same time reduce the cost of the same.

Viith this and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings which show a preferred embodiment ot my device and then specifically pointed out in the claims which are attached to and form a part of this application.

ln the drawings z-Figure 1 is an elevational view of a stanchion equipped with my improved lock. Fig. 2 is a top plan view thereof. Fig. 8 is a similar view with a lock and stanchion in open position. Fig. #t is a vertical sectional view on the line t-t ot' Fig. 1. Fig. 5 is a cross sectional view on the line 5-5 of Fig. 1. Fig. G is a detail view of the lock removed. Fig. 7 is a cross sectional view similar to Fig. 5, showing the lock in open position. Fig. 8 is a cross sectional view on the line 8 8 of F ig. 2.

Referring more specifically to the drawings, in which similar reference numerals designate corresponding parts throughout, 10 designates the lower horizontal members and 11 the upper horizontal members of the stanchion frames which horizontal members are connected at their opposite ends by the vertical members 12 having their ends secured by said horizontal members. The movable stanchion bar 13 has its lower end pivoted between the lower members 10 while its upper end is adapted for movement bctween the upper or horizontal members 11 and adapted to be locked in position by means of my improved locking mechanism which will now be described.

My improved lock is formed of two pieces 14 and 15 of spring metal preferably of circular form in cross section. The ends of the members or pieces 141 and 15 are provided with the eyes 16 and 17 through which the pivot pin 18 is passed, said pin 18 extending vertically through the front of the member 11 near one end thereof and through the transverse horizontal opening 19 in the member 11, in which opening the eyes 16 and 17 are positioned, the member 141- being positioned in front of the member 11 while the member 15 is rearwardly thereof. Adjacent the eye 16, the member 14 is bent at a right angle and normally engaged against the front face ci the outer member 11 and a spaced distance from the opposite end of said member 14, the latter is again bent at a right angle and extended rearwardly through the opening 20 in the member 11 in the path of movement of the outer end of the movable stancliion bar 13, said end terminating in the eye 21 adjacent the rear member 11. The member 14 is provided with an otl'set portion 22 intermediate its bent ends to form a handle by means of which the lock may be opened, as will later be clearly apparent. lassed through the eye 2l of the member 14 and through the eye 23 on the end of the meinber 15 opposite the eye 17 is a connect-ing bolt 24 to connect the members 14 and 15 and the member 15 is provided intermediate its length with a forwardly directed lug portion 25 which is engaged in the opening 26 in the frame member 11, between the openings 19 and 20. A coil spring 27 is engaged around the lug 25, and bears against the plate 28 employed for closing the forward end of the opening 26. The spring 27 serves to resiliently retain the lock members 14 and 15 in the path of movement of the upper end ot the movable bar 18, the main portion of the member ll engaging against the outer face of the member 11 and against the plate 28. To release the member 13, the handle portion or oifset portion 22 is engaged and the members la and 15 swung forwardly upon the pivot pin 18 thus compressing the spring 27 and drawing the cutting away a portion of said upper end to allow the bar to properly ride over the lock member 15 when said lock is in open position.

It will be understood that vwhen the stanchion is in open position, the upper end of the member 13 will rest between the ends of the members 14 and 15 connected by the pin 1S Vand the adjacent corner of the frame and the members 14 and 15 will assume their inner or vlocked position being automatically swung `.to said posit-ion by means of the spring 27. r

From the foregoing it will be evident that I have provided a spring st-anchion lock of extremely simple construction and operation -tha-t will be highly efficient and eective in use. It will also be evident that this lock may be readily and cheaply applied -to stanchions now in use. Further it will be evident that minor changes in the details of construction may be made if desired without in the slightest degree departing from the spirit of my invention.

What I claim is 1. In a stanchion lock, the combination with the upper forward horizontal frame member and the movable stanchion bar, of a forward lock member having one end bent rearwardly and extended throughthe frame member and in the path of movement of the movable bar, a rear lock member having its opposite ends connected to the ends of the forward lock member, said lock members being pivoted at one end in the frame mem- 40 ber, a lug projecting forwardly from the rear lock member and into the frame member, and means engaged around the lug and pressing against the rear member to resiliently retain thel` lock in closed position. 2. In a stanchion lock the combination with a stanchion frame and movable bar, of a rear lock member having a lug projecting therefrom and the forward member having one end connected with the rear member, 50.

said forward and rear loclr members being pivoted in the frame at their connected portions7 the spring engaged around the lug of the rear member for resiliently retaining said member in spaced relation to the frame, the opposite end of the forward lock member being bent rearwardly and secured to the rear locli member, and means carried by the forward lock member for withdrawing the lock members from the path of move- G0 ment of the movable bar.

In testimony whereof, I afiiX my signature, in presence of two witnesses.

MIL() B. EINER.
